Tumly

Tumly is a 2.5D physics survival game about a humble rolling ball and a very long way down.
Guide Tumly across drifting, bouncing platforms, ride your momentum instead of fighting it, and
survive one treacherous biome after another — because the only real rule is: don't fall.

Keep rolling
Tumly can't fly and can't stop on a dime — it rolls. Platforms float, collide, and trade
momentum like billiard balls, and you're just a passenger learning to steer. Read the physics, time
your moves, and carve a clean line through the chaos.

Earn your belts
Your lives are judo belts, ranked white to black. Climb the ranks and Tumly unlocks new powers tied
to each belt — jump, reverse gravity, freeze the platforms, float, and more. Pop collectible bubbles
for passive perks like a shield, a battery, or extra grip. Fall in, and — depending on your
difficulty — a belt is the price.

Nine biomes, nine ways to fall
Green Pastures — where every roll begins.

Desert Dunes — crumbling sand platforms over hungry quicksand.

Frozen Wastes — shearing ice, freezing water, and a chilling slowdown.

Lava Fields — melting ledges and walls of fire.

Dark Forest — ghostly platforms and a forest floor that hides a pit.

Monopole Match — magnetic platforms you must steer to a single colour.

Crystal Caverns — fracturing crystal that shatters if you linger, on ice-slick footing.

Power Pool — roaming lightning in a charged arena.

Cloud Heaven — wind-blown clouds and the final climb to the sky.


Three ways to play
Gold — the full challenge. Every death costs a belt; run out and it's game over.

Silver — belts only rise, never fall. Climb without the sting.

Bronze — start as a black belt with every ability unlocked. Pure, relaxed rolling.

Each mode keeps its own leaderboard, so there's always a score to chase.
